FASTENING- DEVICE FOR IDEMOUNTABLE RIMS.

Application filed March 9, 1923. Serial No. 623,851.

considerable time and labor are necessary to perform the operations, in addition to which special tools are required.

It is one of the objects of the present invention to provide an improved sin'iple7 du-` rable, and compact fastening device by means of the use of which the rim may be readily and quickly attached to and secured upon the Wheel and as readily removed therefrom Without necessitating the use of any special tools, and at the same time insuring that the rim .Will be properly positioned upon the Wheel, which latter is not always the case with the fastening devices employing the Wedge shaped elements which are usually forced between the Wheel `felly and the rim.

To the attainment of these ends and the accomplishmentof other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination, and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawing illustrating this invention and in which Figure 1 is a side elevation partially broken away of a portion of a Wheel having a rim secured thereto, constructed in accordance with the principles of this invention.

Figure 2 is a view partly in elevation and partly in vertical. section of one form of fastening device.

Figure 3 is a view similar to Fi gure 2 of a modified form of the invention.

Figure 4 is a detail perspective vieiv of a portion of a Wheel-rim.

Figures 5, 6, and 'i' are views of details.

Figure S is a viciv partly in side elevation and partly broken aivay of a Wheel having the fastening devices applied thereto.

Referring more particularly to the dra-vw ing the numeral 10 designates generally a ivheel of any desired construction but in the present invention the Wheel is shown provided ivith spokes, 11.

The rim of the Wheel is provided with any number of casings 12 according to the number of fastening .devices it is desired to use and these casings 'are formed in any de- Sired or suitable manner preferably by be ing formed integral therewith. As the construction of each fastening device is the same the description of one will apply to them all. The casing is provided with a recess 13 therein opening through the top thereof as at 1li and the portion of the rim of the wheel adjacent said casing is preferably recessed as at 15 for a purpose to be hereinafter set forth. rlhe recess 13 in the casing 12 opens through the bottom of the casing and is preferably reduced adjacent its bottom to form a shoulder 16..

Arranged Within the casing is a bolt 17, the end 18 of Which projects through the bottom of the casing and the end 19 projects through the top of the casing and is adapted to be extended beyond the periphery ofthe felly of the Wheel.

A coil spring 2O is arranged Within the recess 13 and encompasses the bolt 17. One end of the spring is secured as at 9.1 to the bolt 17 and the other end 22 of the spring is anchored in any suitable manner to the casing, preferably by inserting the end of the spring in a recess 23 in the bottom of the recess 15.

The spring 2O is of such a length that the bolt 17 may be shifted longitudinally with respect to the casing to expand the spring 20 Vand to permit the spring to contract in a manner to be set forth. A suitable plate 211- of a size and configuration to iit Within the recess 15 is provided and is secured in position in any suitable manner such as by means of fastening screvvs ../.5 passing through suitable openings E26 in the plate. rlhe plate is provided ivith an opening- 27 therethrough adapted to register with the opening lll in the top of the recess 13 and the diameter of the opening 27 of the plate 24E is preferably considerable less than the diameter of the openingv 14 and is only slightly greater than the external diameter of the end 19 of the bolt l'which is adapted to pass through the opening 27. rlfhe plate 24 is of a thickness that when inserted in the recess 15 the upper face thereof ivill be tiush with the periphery of the felly.

An operating lever 28, preferab provided with a laterally deflected biiurcated extremity 29 is provided for shifting the bolt 19 in one direction. This extreniitv .29 of the lever is provided ivith cam shaped portions 30 and the lever is connected ivith the extremity of the bolt 17 preferably by means of a pin 81, and which pin may be held in position by means of suitable cotter pins 32, or other suitable devices which will
